Kristel Mae Tagle Bs BIOLOGY III Planet Earth Earth is the third planet from the sun. The place where many organisms exist‚ enhance with the beauty of nature. Packed with rich biodiversity‚ streams and rivers. Have you seen this place before? Maybe yes‚ but for how long? How much it matter to us if it is lost? What can we do to save them? Those are questions that that will hopefully strike our nerves. In this new millennium‚ many changes have occurred that altered the condition of the nature

When Johannes Kepler was born in the late sixteenth century‚ scientists believed that planets in the solar system traveled in circular orbits around the Earth. The occasional problem was solved by the addition of miniature circles test — epicycles — to planetary paths. But Kepler not only adamantly defended the idea that planets orbit the sun‚ he also revealed that their paths were not perfect circles. His descriptions of planetary motions became known as Kepler’s laws. Born in December of 1571‚

The Earth as a Planet It is important to look at the Earth in its context as only one of the nine planets which make up the solar system. This is an introduction to the Solar System‚ its formation‚ and composition‚ with special emphasis on the "terrestrial" or "inner" planets. I take a kind of historical approach‚ noting the patterns and regularities observed‚ for example‚ by Tycho Brahe‚ described by Johannes Kepler‚ and explained by Sir Isaac Newton. Laplace and even the philosopher Immanuel

Due to its size and composition‚ the Moon is sometimes classified as a terrestrial "planet" along with Mercury‚ Venus‚ Earth and Mars.<br><br><b>Origin of the Moon</b><br>Before the modern age of space exploration‚ scientists had three major theories for the origin of the moon: fission from the earth; formation inearth orbit; and formation

humans can survive for long periods in space and even travel to other planets in the future. If space exploration is halted‚ this valuable knowledge will never be acquired. It is true that environmental destruction is also a serious issue‚ but it is also true that we remain dependent on our environment if we never accept the challenge of exploring other worlds. In conclusion‚ while we undoubtedly face serious problems on our own planet‚ it is imperative that we continue to explore space. This will promote

many do not know or realize is that the planets of the solar system make music. Sounds given off by the planets do not exist in the most conventional way that is seen on earth. Rather‚ sounds exist as electromagnetic vibrations emitted by the planets and trapped radio waves bouncing between each planet and its atmosphere (Millis). These electromagnetic vibrations and radio waves are not audible to the human ear so they cannot be heard if orbiting the planet. So‚ specially designed instruments are

If there is enough material in the protostar‚ the gravitational collapse and the heating continue. If there is not enough material in the protostar‚ one possible outcome is a brown dwarf (a large‚ not-very-luminous celestial body having a mass between 1028 kg

They conquered the virus by taking the serum from the host after they caught it and injecting it into all of the sick patients. “The single biggest threat to man’s continued dominance on this planet is the virus.” ~Joshua Lederberg I do and I don’t agree with this quote. I agree with it because‚ at any time an epidemic like the one in the movie could break out and someone may not be able to find the host or create a medicine for it‚ so that

Colonization of Mars What does a planet need to have in order to support life? Earth is unique in our solar system because it is the only planet that is supporting life. Some scientists go so far as to say that the Earth is a “perfect planet” because it has features that are the perfect environment for living organisms; these features include our atmosphere‚ water‚ and a single moon. Earth is also in a place in our solar system where the Sun gives off the right amount of energy to drive the

Neptune is the eighth and farthest planet from the Sun in the Solar System. Named for the Roman god of the sea‚ it is the fourth-largest planet by diameter and the third largest by mass. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus‚ which is 15 times the mass of Earth but not as dense.[12] On average‚ Neptune orbits the Sun at a distance of 30.1 AU‚ approximately 30 times the Earth–Sun distance. Its astronomical symbol is ♆‚ a stylized version of the
